What is an online alarm?
Online alarm clock is a web tool designed to alert an individual or group at a specified time. It is similar to an online countdown timer, but the difference is that online timers are used for time duration, whereas online alarms are used for specific times. Online alarm clocks don't require special devices or special software (alarm clock app) installed on your computer, notebook or mobile phone. We need only access to the internet and a web browser. We don't always have our mobile phones on us or we are not always allowed to use them and the installation of applications is not always the optimal solution. We can set an alarm clock for a specific time - hour and minute. When the time comes and the info message appears than the online alarm starts ringing.
Online alarm clock can be used for many different activities. Many people set alarm clocks when they go to sleep and want to wake up, however this is only one possible utility. We can also use it when:
- we want a reminder about an appointment or a priority on our todo list for example when we want to go to lunch or dinner, pick up children from school, go shopping, cook or bake something, go to the gym to train, do some sport or do our homework
- we are at our computer and need to do something at a specific time
How to set my alarm
- Our first step is to set the alarm clock for a specific time, so we choose the appropriate hour and minute.
- Next we will see the alarm's settings screen on which every individual alarm has its own settings—ring tone and custom message. These settings are automatically saved when the alarm starts.
- We can test the alarm by clicking the button Test alarm. It is advisable to test the alarm before we use it, so we can see how it works, how it sounds, and how the message is displayed.
- The alarm is then activated by clicking the green button Start alarm.
- To set a different alarm (different hour and minute), click the button Use different online alarm.
- When an alarm is active, the widget shows the current time, the alarm time, and the remaining countdown.
- To cancel an active alarm, click the button Stop alarm.
- Click the Edit button to show or hide the alarm's settings.
- When the time comes, your message is displayed, the alarm rings, and you can stop or snooze it.
Frequently asked questions
- Is the online alarm clock free?
Yes. You can set and use the online alarm clock for free. No account or app download is required. Open the page, choose the time, and start the alarm.
- Will the alarm work if I close the browser or tab?
No. The alarm only runs while the page is open in your browser. Keep the tab with the alarm active (or at least the browser open) for the alarm to sound. On some devices, sleep mode or locking the screen can also stop sound.
- Can I set different sounds or messages for each alarm?
Yes. Each alarm time can have its own ringtone and message. Use the settings (gear) button to choose a sound and add a label or note. These settings are saved automatically when you start the alarm.

Select the hour and minute you want the alarm to go off. Optionally open settings to set a sound and message. Click "Start alarm" to activate. The widget will show a countdown until the alarm rings.
- Can I use the online alarm on my phone?
Yes. The online alarm works in mobile browsers. Note: some phones mute or pause sound when the browser is in the background or the screen is locked, so keep the page visible or check your device settings for best results.
- Why didn't my alarm go off?
The alarm only runs while the page is open. Keep the browser tab with the alarm active (and avoid closing the browser or putting the device to sleep). On PCs, sleep mode can stop the alarm—disable sleep or keep the alarm tab visible. Test the alarm before use and ensure your volume is on. On mobile, keep the app in the foreground or the screen on for reliable ringing.
- Are my alarm settings saved? Can I bookmark an alarm?
Yes. Settings (sound, message) are saved per alarm time when you start the alarm. You can see and manage them in the "Saved alarms" section. Each alarm also has its own URL—bookmark it (e.g. set alarm for 7:00 AM) and your settings will load with one click. For multiple alarms at once, open different times in separate browser tabs.
